John McEnroe

**John Patrick McEnroe Jr.** (born February 16, 1959) is an American former professional tennis player known for his shot-making and volleying skills, his rivalries with Björn Borg and Jimmy Connors, and his confrontational on-court behavior, which frequently landed him in trouble with umpires and tennis authorities. McEnroe is the only male player since the inception of the ATP rankings in 1973 to simultaneously hold the world No. 1 rankings in both singles and doubles. He won 77 career singles titles, 77 doubles titles, and 1 mixed-doubles title during his ATP Tour career. His singles match record of 82–3 in 1984 remains the best single-season win rate of the Open Era. He has stayed active in retirement, often competing in senior events on the ATP Champions Tour, where he has won 25 titles. He also works as a television commentator during the majors. McEnroe was born in Wiesbaden, West Germany, to American parents. McEnroe's father was at the time stationed with the United States Air Force. When John was about nine months old his family relocated to New York. McEnroe began playing tennis at the age of eight, and gradually moved up the ranks of junior tennis and later professional tennis. He attended Stanford University for a year before turning professional.
